Techniques et résultats de l'échodoppler dans l'exploration de la vascularisation rénale et de l'appareil urinaire

The indications for Doppler ultrasonography in urinary tract imaging have been diversified during the past decade. This technique can be used for the diagnosis of vascular disorders involving the renal pedicle or the intrarenal vascular bed, the diagnosis of some nephropathies, in the evaluation of renal tumours and several urinary tract disorders including lithiases, acute obstruction or vesico-ureteral reflux. It benefits from some recent technical improvements and the development of ultrasound contrast agents.
